The Spain international has emerged as a key player over the last two years, having joined the Arsenal academy from Barcelona as a teenager.

Barcelona had expressed interest in Bellerin after Dani Alves left for Juventus, sparking fears he may follow in the footsteps of Cesc Fabregas and return to his boyhood club. Former Barcelona manager Pep Guardiola was reportedly also keen on bringing Bellerin to Man City.

However when announcing the new deal on social media, the 21-year-old said he had no plans to leave.

"Hello, everyone," Bellerin said in a video posted on Twitter. "Sorry to keep you guys waiting. I've had a very big meeting next door, so I just wanted to say that I just signed my new deal with the club so I'm really, really, really happy.

"As you know I've been here for a long time and I feel like this is my home and it was the right thing for me to do. So I'm very happy to still be a Gunner for many more years."

He added on Facebook: "A lot has changed in five years since I first joined the club. This is my home. The club who gave me my first opportunity. The club I will be at for many years."

Bellerin's contract is the first of many Arsenal hope to extend this season. Negotiations are still being held with star duo Mesut Ozil and Alexis Sanchez over new long-term deals, while manager Arsene Wenger's future is also up in the air after his contract expires next summer.
